Interface FSStringConstraint

All Superinterfaces:

FSConstraint, Serializable

public interface FSStringConstraint
extends FSConstraint

Interface for a String constraint. A String constraint supports equality testing to a given string. After creating this constraint, use the equals(String) method to specify the string that the constraint uses in its testing.

To use the constraint, invoke its match(String) method, passing the value to test. You can also embed this test with a path specification, using the ConstraintFactory.embedConstraint(FeaturePath, FSConstraint) method, and use it to test feature structures, or combine it with other tests using the ConstraintFactory.and(FSMatchConstraint, FSMatchConstraint) and ConstraintFactory.or(FSMatchConstraint, FSMatchConstraint) methods.

Method Summary

Modifier and Type	Method and Description
void	equals(String s) String value of matched FS must match input String.
boolean	match(String s) Check if String matches defined constraints.

Method Detail

equals

void equals(String s)

String value of matched FS must match input String.

Parameters:

s - The string that the matched FS must equal.

match

boolean match(String s)

Check if String matches defined constraints.

Parameters:

s - The String to be checked.

Returns:

true iff the String satisfies the constraints.
